Energy Recovery Ventilation
Panasonic have a range of Energy Recovery Ventilation units for use in domestic or commercial applications.
These use very energy efficient counter flow heat exchangers to transfer heat to fresh air, being brought in for ventilation purposes, from the stale extract air.
In cooling applications the ERV works in reverse, using the stale room air to cool down hot fresh air. In addition the ERV has a bypass damper which, when activated, will bypass the heat exchanger to provide fresh air 'free cooling'

The ERV system does not come with a controller.
In most applications customers use a simple 'light' switch to turn the ERV on and off. Sometimes they use a second to switch between high and low speed when the unit is running.
An alternative is to use the external fan interface in a PACi or ECOi indoor unit to control the ERV using the ventilation switch on a CZ-RTC2 controller. This is easy and we are very familiar with how to do it so please ask us for details when you purchase your ERV unit.
Finally we have two useful controllers available that can be used with the ERV to significantly reduce energy use.
We have an air quality controller which can be used to turn the ERV on and off based upon measured air quality rather than with an on / off switch. This means that the ERV only runs when it is needed. As you can imagine the potential savings here are large.
We also have a free cooling controller to operate the damper in the ERV if cooling is required and available using fresh air. Once again more potential savings.
Details of these controllers are on our Medal Controls website here
ERV system with cooling and heating for use with ECOi & ECOG
In addition to the standard ERV system we also have a 500, 800 and 1000 m3/hr ERV system with DX coil and able to be controlled like a standard indoor unit rated at 3.7KW, 4.9KW and 5.6KW respectively. Details on demand.
